How DJVU turns into PNG: document page rendering
Converter.now interprets a scanned-document format combining high-compression page imagery with optional OCR text and navigation, composes its visible page, and encodes that appearance as PNG. Objects that exist outside the painted page - Structure, formulas, controls, or navigation - Do not become equivalent image features. The DjVu document reader enumerates bundled pages and their foreground, background, mask, OCR-text, outline, and annotation components independently. PNG output preserves the exact raster samples with optional full alpha and color metadata, though file size, palette reduction, the lack of animation, and profile handling all still vary by writer.
Starting model: a scanned-document format combining high-compression page imagery with optional OCR text and navigation. Rendered result: losslessly encoded pixels with full alpha transparency.

The delivery decision for this DJVU to PNG route
PNG belongs in workflows that need a visual page, not an editable DJVU object model.
What changes between the DJVU model and the PNG deliverable
- PNG supports alpha transparency that DJVU never had, so any transparent areas in the result are newly created, not carried over from the source.
- Because PNG is not inherently page-based, a multi-page DJVU may render as separate files or a representative page.
- Metadata handling differs between DJVU and PNG; do not assume every application-specific field carries across untouched.
Acceptance evidence for the converted PNG
Record the DJVU evidence before conversion
Verify page count, order, image clarity, searchable text, bookmarks, annotations, and printing.
Test the PNG file in its receiving workflow
Inspect transparent edges, gradients, exact dimensions, color, and small text at 100%.
Reading DJVU correctly and satisfying what PNG expects
What can fail when DJVU document format is interpreted
Raster conversion can discard hidden text and outlines, while document conversion may not preserve the original foreground/background layers.
What Portable Network Graphics cannot safely promise
PNG is inefficient for many photographs, and indexed optimization can reduce a smooth palette even without JPEG-style loss.
How the PNG writer handles this route
losslessly encoded pixels with full alpha transparency is what gets written, labeled as image/png. Whether that actually opens depends on the receiving application, not on the file extension.
